ir co2 sensor quartz

Low Cost IR CO2 Sensors -

This CO2 sensor module is designed to monitor 0-5,000ppm carbon dioxide levels using a dual beam light source and NDIR sensing technologies. By using the dual-infrared source principle, the CU-1107 sensor compensates for long-term drifts by design. Dual beam detection allows for superior stability and better accuracy over the predicted 10 year lifespan of the sensor. It can achieve equivalent ...

Wireless CO2 Sensor Reference Guide

persive infrared (NDER) technology. The sensing ele- ment is a pyroelectric device that senses the carbon dioxide gas concentration by measuring the amount of infrared (IR) energy absorbed by CO gas in the probe housing. The infrared (IR) source at one end of the probe is a lamp with a quartz envelope and a gold plated reflector. The sensitive thermopile element at the other end of the probe ...

How does an NDIR CO2 Sensor Work? |

An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for small-footprint CO2 sensors. These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module.
